I have tried multiple times and Deterrence doesn't seem to work for me, the timing isnt that crazy hard and I have popped it multiple times before getting the debuff. So I dont think it does work, but I may just be bad!

Ice Block, Divine Shield, and Cloak of Shadows for Boomkins via Symbiosis works. You have to make sure that the immunity is active on you before the debuff is applied. If you're waiting til you see the blue arrow or his cast bar starts, you're going to have to have an extremely quick reaction time and still be fighting server latency and personal latency.

What is easier? If you have a rogue in your group, Smoke Bomb Frost King, Put the SB on top of Frost King while all range are outside. So long as Frost King has Smoke Bomb on him while he casts it, no one will get Frostbite.

as the others allready said, deterence doesnt work, but camouflage does work! just hit it in time before the debuff gets applied and you wont get it, bcz he cant target you

i did macro stopattack and stopcast into it and it does work like a charm, dont know if you need to, but i have.

Oh god this is absurd. I swear I didn't see any note about this change! We have 2 hunters in group and I'll let them know about this.

But how does it work? Like if he casts on you while camouflage then there will be no frostbite, or he will pick another target since he can't target you? If it's latter then it doesn't make that difference in our raid (maybe even makes it worse) cause we got them with a brutal strat: just let the person die and brez... We only get one frostbite per fight so if you are gonna die to something, that has to be the frostbite anyways lol.

you don't have a mage, rogue, or holy pally and you have 2 hunters? I'm assuming which is a 10 man.

he tries to apply the debuff and just cant, thats just the hunter version of iceblock/smokebomb/whatever works too, nothing of the retargeting sorts happens, just good clean no frostbite

Hand of Protection, if cast before frostbite goes out, works as well. You can either watch for the blue arrow to appear and cast it then, or you can pre-cast it on those that don't have immunities. Either way, as long as HoP is up before Frostbite is applied, it will work.
